Portals and spaced repetition

Hi! I am trying to study specific documents by bringing them into a document with portals. It doesn’t seem to work when I try to use spaced repetition. I just want to have documents set up visually so I can slowly add more cards. Is this by design? or am I doing something wrong? Is there some other approach I should be using. Thanks so much for any help you can provide.

You may either use the portal’s dots menu to turn it into a queue and study that or unfold the portal’s contents and study the document that contains them from its dot menu.

Thank you, UMNiK! I figured it out last night. Appreciate your help.
